发明名称 Method and apparatus for providing faster convergence for redundant sites
摘要 A method, apparatus and computer program product for providing convergence for a dual-homed site in a network is presented. An occurrence of a failure between a first Provider Edge (PE) device and a first Customer Edge (CE) device in communication with a dual-homed site is detected. A determination is made whether an alternate route exists for the dual-homed site in a routing table associated with the first PE device. When an alternate route exists then a routing entry associated with the first CE device in a routing table of said first PE device is kept from being deleted for a predetermined amount of time, the routing table is modified to reference the alternate route, the routing entry is rewritten to perform a POP and lookup in a VRF table of the first PE device, and the routing entry is deleted after the predetermined amount of time has elapsed.
